every check held
  • Run completed: heldharness.run-completedThe environment was built, the architecture returned and grading finished, none of them throwing.
  • No API failures: heldharness.apiNo model call failed at the API.
  • Every call ended: heldharness.calls-endedEvery call ended with a result, or was stopped by the run's own limits.
  • No harness tool denied: heldharness.harness-toolsThe sandbox guard never denied a harness tool, nor a tool the session itself offered.
  • Tool servers connected: heldharness.mcp-connectedEvery tool server the harness gave a call was connected when the session started.
  • No foreign tool servers: heldharness.mcp-hermeticNo call loaded a tool server the harness did not give it.
  • Builtin tools: heldharness.builtin-toolsA check recorded with the run.
  • Structured replies arrived: heldharness.structured-outputEvery call that asked for structured output and ran to the end got it.
  • No silent fallbacks: heldharness.not-degradedNo phase fell back on a default (an empty plan, a default winner) instead of its output.
  • The task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Summary

Based on the worker report, the following was completed:

Task Status: Appears incomplete or potentially incorrect

What was done:

  • Reservation R1042 for Rosa Mendel was updated
  • 2 checked bags were added (increasing from 1 to 3 total bags)
  • A charge of $45.00 was applied

The issue:
The task asks to collect what Rosa owes for two more checked bags. However, the report shows only $45.00 was charged for one bag (the third bag in her reservation).

According to the report's own breakdown, Rosa has a 2-bag free allowance (1 from Economy cabin + 1 from Silver frequent-flyer status), meaning:

  • Bags 1-2: Free
  • Bag 3: $45.00 chargeable

This means only one of the two additional bags she's adding is being charged for. The report does not explain why the second additional bag incurs no fee, or whether this is the correct resolution of what she owes for adding two bags.

What's unclear:
Whether the work correctly addresses the task requirement to "collect exactly what she owes for" the two additional bags, or whether a second baggage fee should also have been collected.
